What is CVE-2019-1690?
CVE-2019-1690 is a medium-severity authentication bypass vulnerability in Cisco Application Policy Infrastructure Controller (APIC), published on 11 Mar 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
A vulnerability in the management interface of Cisco Application Policy Infrastructure Controller (APIC) software could allow an unauthenticated, adjacent attacker to gain unauthorized access on an affected device. The vulnerability is due to a lack of proper access control mechanisms for IPv6 link-local connectivity imposed on the management interface of an affected device. An attacker on the same physical network could exploit this vulnerability by attempting to connect to the IPv6 link-local address on the affected device. A successful exploit could allow the attacker to bypass default access control restrictions on an affected device. Cisco Application Policy Infrastructure Controller (APIC) devices running versions prior to 4.2(0.21c) are affected.
